What’s Living in YOUR Shower?
Student Laboratory Kit
By: The Flinn Staff
For many people, the thought of microorganisms all around us, all the time, is just gross—but it is a fact of life! Introduce your students to the diverse and fascinating world of environmental microbes “hiding in plain sight” with this hands-on culturing activity . Students develop sterile technique skills as samples are collected from different surfaces outside of class and cultured . The resulting microbial colonies are then carefully observed and diagrammed to compare and contrast their growth characteristics . Students discover that microbes, like people, come in all colors, shapes and sizes and indeed have unique “personalities .”
Complete for 30 students working in pairs. An autoclave or pressure cooker is required. The availability of dissecting microscopes will make it easier for students to observe details in the growth patterns of the colonies.
Sam ’n Ella’s Café—Simulated
Food Poisoning Laboratory Kit
By: The Flinn Staff
Although microorganisms live very comfortably on and/or in almost everything imaginable, most people do not give that fact a second thought when they go out to eat . Initiate a lively discussion about the safe handling of food after students “eat” a buffet meal at Sam ’n Ella’s Café and participate in a true-to-life simulation . Once food from each of six food categories has been selected by each student, the “food” (water) on their plates (cups) is tested to determine who and how many people are “sick .” Then students play the role of food detectives to determine which food is contaminated and which “bacterium” may have caused the illnesses .
Complete for 30 students working individually. No living bacteria are used and no real food poisoning will result from this activity. Testing the “food” for contaminants involves detecting the presence of a base (the food “contaminant”) using a pH color indicator.
Antibiotic Resistance—
Super Value Laboratory Kit
By: The Flinn Staff
Make sure to finish your medicine! Many prescription bottles warn of the importance to take on time as directed and to finish the entire contents of the bottle . What happens if the patient misses a dose or if he decides to stop taking the medication? Students will obtain data by tracking the population of three different strains of bacteria, represented by three different colored bingo chips, throughout the antibiotic treat- ment . When the antibiotics are taken on time, every time, the bacteria will gradually become eliminated starting with the least resistant to most resistant . However, if a dose (or more) is missed the bacterial populations will grow . Students will construct a graph of their results and analyze the effects of the antibiotics on three strains having differ- ent antibiotic resistance levels . Witness students’ expressions as they finally understand the why the elusive prescription directions are so important! Includes pre-activity questions, reproducible student work- sheet and post lab questions, and Instructor’s Notes .
Super Value Kit is complete for 30 students working in pairs. All materials are reusable!
